Camera Mount

I have a 2 Axis camera mount on the way. Will I be connecting a lead from my receiver to X3 on the WK-M to adjust the pitch manually. Will anything need to be connected from my receiver to X2. Does the WK-M handle the Roll automatically thru the software setup.

Thanks

After you conenct the roll and pitch servos to the appropriate ports on the WKM control box it will automatically level both axis. Be aware that you need to turn on the gimbal in the Assistamt softwaare and increase the gimbal gains before it will work. I've found that the servos will not move at the default gain setting of 2, typically the minimum gain setting is going to be at 20 or higher depending on the mount and servos used.

Sounds good I will bring up to 20 and see what happens. If I run cable from Aux 3 on my receiver to X3 on the WK-M will I be able to manually control the vertical to change the angle of the shot with the knob on the transmitter.

You will still have tilt control via a TX channel, the port you plug into depends on the configuration, quad, hex, X8, etc. and if you're using the power module with monitoring.

is it possible to use a 3 axis gimbal with the wkm?

For that you will need either a Picloc 3X to control all three axis or a second TX/RX for a camera person to operate the pan and manual tilt functions while the WKM takes care of the automatic tilt and roll compensation. Same is true for pretty much every other flight controller out there so it's nothing unique to the WKM, I don't know of any that are also capable of doing pan compensation as the multi is flying, they all are programmed for only two axis of motion compensation and assume the mount will always be facing in the same direction in relation to the flight controller.

Just please don't power your camera servos through the WK-M. Both myself and Boris burnt out the PMU doing that! Use a separate ubec...

How do you do that. My UBEC has a male servo type plug on the end like the servos do for it's output. The servos have to plug in to the MC so I'm not sure how to wire it up.

Thanks

I haven't done mine yet, but I assume you have to cut a few wires and make up a custom loom. Signal to the WKM and power to the ubec...hopefully someone has done this already and can post a description and pics for both of us!

The servo wire from the Ubec connect a Y lead to it and then remove the white signal cables from the servos and connect into the Wookong camera gimble ports , and the + and - of each servos into the Y leads .
Castle creations do a good bec , with Voltage programmable from 5v to 9v I think . Droider uses one so might be worth asking him if he can take a piccy .

Won't the MC need to see the White Signal Wire and a Ground wire from the servo?

I have the CC BEC on both of my AV130, one on the MK Droidworx and the other on the WKM. The newer AV130 is using the CC BEC Pro mounted to the top of the 130 and hidden away between it and the lower frame plate. The Pro has two outputs and can handle 2x the current of the smaller version which is what I'm using with the other mount on the MK, either one will do the job though you will need the the CClink to program either one, I have both set for 6 volts.

With the Pro its a very easy setup, I just removed the signal wire from the servo's connector and split it away from the rest of the wires for a couple inches and put it into an empty servo connector I had in the spares box which then plugs into the controller. The remaining power wires then simply plug into the feeds from the CC pro. If you use the smaller CC BEC you will need a Y harness to connect both servos to the single power feed but the rest of it is still the same. If you find the signal wire isn't long enough to reach the controller a regular servo extension lead will work fine to make the connection.

No need to worry about ground connections as long as the BEC is connected to the same battery powering the rest of the system, the ground will then be common for all of the circuits.

Thanks Ken....

I think I will use the BEC and not let the PMU handle the servos. I do have the small one already so maybe I will just use it.

Thanks

Hey Ken...

Won't I need a female to female extension for the Pro or a female to double female for my smaller bec to connect from the servo red/black to the BEC

Thanks[
